I have a link on one page which looks like this:
http://www.domain.com/sample-link#product_id
and on the other page (sample-link), I have this input field:
<input type="text" name="name" value="name" />
So, when I click the link from the first page, I want to open the "sample-link" page, and autofill the name field with the "product_id" text. Any ideas how can I make this?
Thanks in advance.
You'll just have to add a tiny Javascript snippet:
if (document.location.hash)
document.getElementById('testbox').value = decodeURIComponent(document.location.hash.substr(1));
For obvious reasons you'll have to adjust the id of the text box.
It gets a bit more complicated in case you'd like to pass more than one value.
The call to decodeURIComponent() is optional, but required in case you're passing characters like spaces or non-alphanumerical stuff (just to be sure).

I'm using Statamic CMS
I've got a checkbox group with two checkboxes, I'd like both of them to be checked before the form will submit.
Setting the field as 'required' half works. The form will error if nothing is checked, but it submits if one of the boxes is ticked.
I can see under the validation tab, there's a list of additional rules. But I'm not sure which rule to use.
If it helps, this is what the HTML checkbox group looks like:
<div>
<label>Contact permissions</label>
<span>Please tick both checkboxes</span>
<label>
<input type="checkbox" name="checkboxes[]" value="gdpr" />
Please contact me with the details I've provided
</label>
<label>
<input type="checkbox" name="checkboxes[]" value="terms" />
I agree with the terms and conditions
</label>
</div>
I'm using the {{ fields }} tag to generate the HTML
Within the CMS, under the validation tab, there's a link to the Laravel docs. As I want to validate two checkboxes, I think I need the required_with: rule, but I can't get it to work...
required_with: is looking for two values, the example shows this:
required_with:foo,bar,..
The values of the checkboxes are, value="gdpr" and value="terms" so I (wrongly) assume this should work...
required_with:gdpr,terms
After saving the changes and testing the form, it still submits? Even though only one of the checkboxes might be ticked...
What is the correct syntax/values to use to get this to work?
:) foo,bar in the docs are field names in your form. What you're doing with gdpr,terms are values.
Plus, since both your buttons are named checkboxes[], the form is validating that if either one is selected, then it should be passed. Hopefully this helps!
I have a country picker in my form like this:
<select class="bfh-countries text-left" name="country" id="country" data-country="DE">
</select>
I can get the value with jQuery like this:
$("#country").val()
but when i try to serialize the form with $("#myform").serializeArray() The value for "country" is an empty string.
How can i fix this?
I ran into this problem and it took me forever to find because there aren't any examples of it. What you really want to do is use data-name="country", which names the hidden variable on the back end as country. For the country picker, you can use the div tag as follows:
<div class="country bfh-selectbox bfh-countries" data-flags="true" data-filter="true" data-name="country" data-country="POSTBACK_VARIABLE_GOES_HERE"></div>
If you do this, you'll find a hidden variable that's added to the page as follows:
<input type="hidden" name="country" value="US">
The value above assumes you selected United States but it is entered as a 2 character code, which could then be entered as data-country above if you need to do server-side validation and display the page again without forcing the user to select the value all over again.
This was seriously a nightmare to find.
Posted this to Play user group; I account for the sole view, so hoping to get a view, or perhaps even an answer ;-)
Nested forms are great, but there's one glitch that adds boilerplate to either javascript or scala templates.
For example, given:
#inputText(field = _form("user.email"),
'_label-> "Email Address*",
'class-> "required email",
'placeholder-> "jdoe#gmail.com"
)
the generated input field is something like:
<input id="user_email" name="user.email" ...>
Now, when you want to validate the email address client-side you then have to reference DOM id: $('#user_email')
Where $('#email') would be more natural.
I know I can set the id attrib manually in the template but would prefer to, by default, have the nested name (user in this case) stripped out from the id attrib.
Looking in github views helper directory, I am not finding where I can get access to the generated id (i.e. which file I need to overload and how).
Anyone know how to pull this off and/or have a better approach?
Here is where the field's ID is auto-generated:
https://github.com/playframework/Play20/blob/master/framework/src/play/src/main/scala/play/api/data/Form.scala#L274
There's not really any way you can override that behaviour, but you could write your own #inputText helper that strips the "user_" part from the ID when generating the HTML.
Basically copy-paste the default helper and replace
<input type="text" id="#id" ...
with your own code, e.g.
<input type="text" id="#processFieldId(id)" ...
or (untested!):
<input type="text" id="#(id.split('_').last)" ...
Then just import your custom helper in your template, and use it just like you would use #inputText.
I have a form and using a normal submit button with no name like this below.
<input type="submit" value="Submit" />
Everything works fine like it is. My question is there a way I can give it a name say random numbers like this below.
<input type="submit" name="R312321321" value="Submit" />
Then when I submit can I get the value of the name of the submit button like if it was a hidden input. I can't use a hidden input for what I'm doing. The reason I want to do the submit button this way is browser macros look for the name. If the name is always changing its harder for their macro to work. Once I get the value of the submit button I can authenticate it which I have something already created just need to get the value of the submit in php.
Thank you
Yes, this would work. However, the spec says otherwise about input names beginning with numbers.
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be
followed by any number of letters, digits ([0-9]), hyphens ("-"),
underscores ("_"), colons (":"), and periods (".").
After you submit the form you will have a key value pair
[312321321] => Submit
im pretty new to jQuery, and i dont know how to do that, and if it can be done without editing manually the plugin.
Assume to have a simply form like that:
<form action="page.php" method="post">
Name: <input type="text" name="Your name" id="contact-name" value="" />
Email: <input type="text" name="Your email" id="contact-email" value="" />
</form>
When you submit it, both in 'standard' way or with ajaxSubmit(), the values of the request take the label of the field name, so in the page.php i'll have:
$_POST['Your name'];
$_POST['Your email'];
Instead i'll like to label the submitted values with the id of the field:
$_POST['contact-name'];
$_POST['contact-email'];
Is there a way to do that with jquery and the ajaxsubmit() plugin?
And, maybe, there is a way to do it even with the normal usage of a form?
p.s: yes, i know, i could set the name and id attributes of the field both as 'contact-name', but how does two attributes that contain the same value be usefull?
According to the HTML spec, the browser should submit the name attribute, which does not need to be unique across elements.
Some server-side languages, such as Rails and PHP, take multiple elements with certain identical names and serialize them into data structures. For instance:
<input type="text" name="address[]" />
<input type="text" name="address[]" />
If the user types in 1 Infinite Loop in the first box and Suite 45 in the second box, PHP and Rails will show ["1 Infinite Loop", "Suite 45"] as the contents of the address parameter.
This is all related to the name attribute. On the other hand, the id attribute is designed to uniquely represent an element on the page. It can be referenced using CSS using #myId and in raw JavaScript using document.getElementById. Because it is unique, looking it up in JavaScript is very fast. In practice, you would use jQuery or another library, which would hide these details from you.
It is reasonably common for people to use the same attribute value for id and name, but the only one you need to care about for form submission is name. The jQuery Form Plugin emulates browser behavior extremely closely, so the same would apply to ajaxSubmit.
It's the way forms work in HTML.
Besides, Id's won't work for checkboxes and radio buttons, because you'll probably have several controls with the same name (but a different value), while an HTML element's id attribute has to be unique in your document.
If you really wanted, you could create a preprocessor javascript function that sets every form element's name to the id value, but that wouldn't be very smart IMHO.
var name = $("#contact-name").val();
var email = $("#contact-email").val();
$.post("page.php", { contact-name: name, contact-email: email } );
This will let you post the form with custom attributes.
